SPECIFICATION forming part of Letters Patent No. 586,167, dated July 13,1897.

Application filed March 8, 1897.

To all whom it may concern:

Be it known that I, FRANK H. DUDLEY, a citizen of the United States,residing at Jay, in the county of Franklin and State of Maine, haveinvented certain new and useful Improvements in Guards for PreventingRolls of Paper from Slipping on Finders; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled inthe art to which it appertains tomake and use the same.

My invention relates to improvements in detachable guards for preventingrolls of paper from slipping on the winder during the operation ofwinding. the core on which the paper is wound is mounted on a shaftadapted to rotate and slide on suitable ways in such position that thepaper onthe roll contacts continuously with a rotating shaft whichimparts rotation to the shaft 011 which the core is mounted byfrictional contact with the paper 011 the core. It is found in actualpractice that after the roll gets to be of considerable size it isliable to slip on the core endwise unless it is held bysome deviceplaced against the ends thereof, and inasmuch as the paper itself mustcontact with the shaft at all times the guard placed against the end ofthe roll must be of a diameter not greater than the roll itself. It isfound in practice that the slipping of the roll on the core doesnot takeplace until after a considerable size is reached, so that at first theguard need not be used. The custom at the present time is after the rollhas been winding for a considerable time to place a wooden disk againstthe end of the roll and hold it in place by a flexible cord secured tothe shaft and allowed to wind around it in contact with the disk. Thisarrangement is clumsy, difficult of application, liable to fail, and isattended with danger to the operator, because it must be done while theshaft is rotating quickly. To provide a positive-acting guard which maybe easily, quickly, and safely applied while the machine is in operationis the purpose of the present invention.

In the drawings herewithinclosed and making a part of this applicationFigure 1 is a plan View of my improved guard placed in position on thewinder. Fig. 2 is a cross-sec- Fig. 3 is a tion taken on line Y Y ofFig. 1.

longitudinal section taken on line X X of Fig. 2, and Fig. i is a Viewof the clampingtool.

In said drawings, A represents the core-shaft of the winder, itsjournals being adapted to slide and rotate in bearings B, and O a shaftagainst which the paper contacts. On the winder-shaft is placed acore-holder D, upon which the core E is supported and over the ends ofwhich the core extends. This holder is provided with a lug F, whichprojects into a socket Q in the core, or vice versa, the exteriordiameter of the core being equal to or greater than that of the body ofthe coreholder. The external surface of the coreholder is threaded, asseen at G. The paperguard consists of a divided nut E, interiorlythreaded, as seen at H, and hinged together, as at I. It is alsoprovided with a pivoted locking-bolt I to lock the two parts together onthe core-holder. Secured to the inner face of said nut is a disk J,having a diameter considerably greater than that of the coreholder,

core-holder by being held by a suitable tool upon said core-holder andallowed to turn on by the rotation of the core-holder. The disk has atthe point opposite thehinge a V-shaped portion removed, as seen at K,which per mits the opening of the nut on its hinge sufficiently to allowit to be placed over the shaft prior to being placed on the core holder.This is necessary because it has to be put in position after the paperhas begun to be wound upon the core and while the core is in rapidrotation, and it will be evident that it could not be placed in positionby being put on over the end of the shaft. The nut has a flange Lthereon, around which a clamping tool M is placed to hold the nutagainst rotation while it is being turned on to the I threadedcore-holder. The disk maybe of Wood or any suitable material and may besecured to the nut in any convenient manner.

Having thus described my invention and its use, I claim-- 1'. In adevice of the character specified, the combination with the windershaftand externally-threaded core-holder mounted thereon, of a divided nutprovided with a di vided disk adapted to be brought into engagement withthe end of a roll of paper while being Wound upon said core,substantially as and for the purposes set forth.

2. In a device of the character specified, the combination with theWinder-shaft and externally threaded core holder mounted thereon, of adivided nut hinged together at one side and provided with means forlocking the two parts together and having on the inner end a guard andon the outer end a flange 10 to receive a tool for holding the guardWhile being placed in position on the core, substantially as and for thepurposes set forth.

In testimony whereof I affix my signature, in presence of two Witnesses,this 1st day of March, 1897.

FRANK H. DUDLEY.
